Abstract (en)
The method involves determining a hydraulically effective cross-section area of bellows (7) which represent size. A valve spring (8) is selected related to its spring action (F3) dependent on that the hydraulically effective cross-section area of the bellows. A valve needle (2) is arranged in the valve body (1) and coupled over the valve spring and the bellows. Axial pressure affects the valve needle which is dependent on a fluid pressure prevailing in a low-pressure range or a high pressure range to open or close the valve.
